# How do you find the area of a non regular pentagon?

## How do you find the area of a non regular pentagon?

The area of an irregular pentagon can be calculated by dividing the pentagon into other smaller polygons. Then, the area of these polygons is calculated and added together to get the area of the pentagon.

### What is the formula for the area of an irregular shape?

Area of the given irregular shape = Area of the rectangle ‘P’ + Area of the semicircle ‘Q’ + Area of the triangle ‘R’ + Area of the rectangle ‘S’. ⇒ Area of the given irregular shape = 48 + 39.25 + 24 + 48 = 159.25 square units.

#### What is the formula for area of a polygon?

The formula to calculate the area of a regular polygon is, Area = (number of sides × length of one side × apothem)/2, where the value of apothem can be calculated using the formula, Apothem = [(length of one side)/{2 ×(tan(180/number of sides))}].

**How do you find the area of an irregular plot?**

How to use irregular area calculator?

- Step 1: Measure all sides of the area in one unit (Feet, Meter, Inches or any other).
- Step 2: Enter length of horizontal sides into Length 1 and Length 2. And Width of the vertical sides into Width 1 and Width 2.
- Step 3: Press calculate button.
- Our Formula: Area = b × h.

**How is irregular polygon measured?**

Polygons that do not have equal sides and equal angles are referred to as irregular polygons. Thus, in order to calculate the perimeter of irregular polygons, we add the lengths of all sides of the polygon.

## How do you find the area of a 4 sided irregular polygon?

To find the area of such irregular quadrilaterals, follow a three-step strategy:

- Divide the quadrilateral into two triangles by constructing a diagonal that does not disturb the known interior angle.
- Calculate the area of each triangle, using formulas.
- Add the areas of the two triangles.

### How do you calculate irregular polygons?

The interior angles in an irregular polygon are not equal to each other. Therefore, to find the sum of the interior angles of an irregular polygon, we use the formula the same formula as used for regular polygons. The formula is: Sum of interior angles = (n − 2) × 180° where ‘n’ = the number of sides of a polygon.
